I just read a pretty interesting paper about spirulina and microglial cells, called “Spirulina and C-phycocyanin reduce cytotoxicity and inflammation-related genes expression of microglial cells” (you can read it here if you are interested in the science).

Microglial cells are the cells found in your brain and spinal cord. They are in charge of the defense and repair in the the Central Nervous System (CNS). They represent about 20% of the cells we have in the brain. They are very important cells!

The microglial cells are macrophages scavenging the CNS to “find and destroy” infectious agents, damaged cells, etc. When they are “activated” they become inflamed. Inflammation is not a bad thing, it’s a normal process in our bodies; it’s your body removing the injurious stimuli and starting the healing process. The problem is when you have too much inflammation (acute vs. chronic).

When the microglial cells are activated, they release a series of factors that are toxic to the neurons. Inflammation is a common denominator of numerous neurodegenerative diseases (that’s all the “neurons diseases” ) such as Alzheimer, Parkinson, Huntington, etc.

In 2012, Dr. Chen and his collaborators published their work in the prestigious Journal of Nutritional Neuroscience showing that spirulina orally administrated may provide protection from neurodegenerative disorders in which microglial activation plays a pathogenic role.

How? Thanks to their anti-oxidative, anti-inflammatory activities and neurprotective effects (via inhibition of COX15 and/or nicotinamide adenine dinucleotide phosphate (NADPH) oxidase enzymes, if you want to know).

So basically spirulina helps our CNS get better and stay fit longer (and also helps reduce the effect of aging)!

Gotta love your Spirulina ♥

If you’ve never taken spirulina before, it is usually recommended to start slowly and progressively increase the dose up to 20 gr/day. You can read this post to know more about how much spirulina you should take.

If you don’t want to take any more “pills” then you can very easily incorporate spirulina in your diet by adding powder or crunchies to your meal. Check out our recipes to know get ideas and share your own creations on this blog for our readers 🙂
